  • a solution generally used for this purpose is to place the patient at greater height.
  • special beds high-low beds developed for home care
  • These beds operate very efficiently but installation on site (for instance in the case of home care) is not simple; they are after all large and heavy and thereby difficult to use in private houses. They furthermore prevent the patient from continuing to use his/her own bed.
  • blocks are available for home situations with which a bed can be placed as a whole at greater height.
  • the object of the present invention is to provide a simple solution for caring for patients at a height, particularly for patients in a home situation.
  • the invention provides for this purpose a method for height-adjustment of a support surface for a patient by: a) combining an inflatable support member constructed from a plurality of separate layers with at least a part of an existing bearing structure for persons, b) filling a single layer of the inflatable support member until this layer has been brought under a determined minimal pressure, and c) repeating step b) by filling a subsequent layer of the inflatable support member until the support surface for the patient has reached a desired height.
  • the inflatable support member is arranged on at least one part of an existing bearing structure, such as a bed.
  • At least a part of an existing bearing structure for persons can also be employed usefully in a situation where a higher bearing structure is (incidentally) required.
  • a significant advantage hereof is that less voluminous objects have to be brought in (with all the associated cost and problems) in order to administer care or to carry out a treatment on a patient lying at a greater height; the displacing of a voluminous special treatment bed is for instance unnecessary.
  • the word "patient” must be widely interpreted; in addition to an ill or bedridden person, it may also refer to a person being massaged, a person being examined and so on.
  • the inflatable support member is coupled to a mattress forming part of the existing bearing structure.
  • the danger of the mattress becoming detached from the support member in undesirable manner is thus obviated. This is for instance possible when the inflatable support member is placed between a bed base and a mattress.
  • Such a placing of the support member has the advantages, among others, that the patient does not have to be aware of the support member in the non-inflated state since he/she is lying on the mattress and in an inflated state of the support member the mattress ensures pressure distribution of the load exerted on the support member by the patient and the mattress.
  • Both the bed base and the mattress of an already present bed can herein be usefully employed to provide increased support for a patient; this can enable optimum use of already available means.
  • the inflatable support member it is also possible for the inflatable support member to be placed on a mattress on the side remote from a bed base.
  • placing of the inflatable support member is very simple; it need only be placed on a bed. It may also be desired to realize a specific contact surface with the patient which differs from an already present mattress, for instance a surface which is less likely to result in bed sores or a surface which can be cleaned more easily.
  • a further increase in the stability of the combination of the support member and the bearing structure in this specific assembly of bed base, support member and mattress can be obtained when the bed base forming part of the existing bearing structure is coupled to the support member prior to carrying out method step a).
  • the inflatable support member is arranged on a surface under at least a part of a bearing structure such as a mattress.
  • the inflatable support member can thus be placed directly on the ground. This can be advantageous if no existing bed base is available at the desired location or when an existing bed base does not provide sufficient stability. It is of course also possible to first arrange on the ground a protective layer on which the inflatable support member is then placed.
  • the inflatable support member is preferably arranged on an existing bearing structure in a substantially non-filled state.
  • the support member thus has a minimal transport volume and is easy to handle.
  • a possible drawback of an inflatable support member is the limited stability of such a support member in a half-filled state.
  • the maximum unstable height is the thickness of a single layer.
  • a pressurized layer does after all derive its firmness from the filling pressure.
  • the invention provides for this purpose a method which is more or less the reverse operation of the height-adjustment of the support surface, by: 1) substantially emptying a single layer of an inflated support member constructed from a plurality of separate layers, which inflated support member is placed on an existing bearing structure such as a bed, and m) repeating step 1) by emptying a subsequent layer of the inflatable support member until the support surface for the patient has been lowered to a desired level.
  • the invention also provides an apparatus for height-adjustment of a support surface for a patient, comprising: an inflatable support member constructed from a plurality of separate layers, and coupling means for coupling the support member on at least one side to an existing bearing structure for supporting patients.
  • an apparatus has a simple construction and can be installed quickly and simply.
  • the separate layers of the inflatable support member are preferably provided with closing means. After bringing to pressure a layer of the support member, the layer can be closed by means of the ⁇ closing means, so that the pressure in the layer is maintained.
  • the inflatable support member is provided with at least one part left clear in the support member such that the part left clear forms a passage through the support member.
  • the support member can discharge moisture and/or vapour (ventilation). A patient lying directly or indirectly on a support member will secrete moisture. This moisture must be drained, which is possible through the part of the support member left clear.
  • Another advantage of the at least one part left clear is that the gas volume of the support member is hereby limited; the support member can be filled more rapidly or emptied more rapidly owing to this measure.
  • the apparatus is preferably provided with feed means for a filling gas.

  • the apparatus For a good stability of the apparatus in an active position, it is preferably provided with coupling means for engaging on a mattress and/or with coupling means for fixing the apparatus to a bed base.
  • Extra stability can likewise be obtained by providing the inflatable support member with elongate strengthening elements, which strengthening elements are incorporated substantially parallel to each other in the inflatable support member. Such strengthening elements still allow the support member to be rolled up in the non-filled state in order to thus minimize the transport volume.
